A combination regenerative and friction braking system for an automotive vehicle includes an active booster master cylinder 32 and a number of wheel cylinders 18 and 20 connected to the master cylinder 32. A brake control unit, hydraulic or electronic control unit (HECU) 38 is connected with brake pipes extending from the master cylinder 32 to the wheel cylinders 18 and 20. At least one pressure reducing valve 34 is positioned in one of the brake pipes so as to allow the active booster master cylinder 32 to actuate selective ones of the wheel cylinders 18 and 20 during regenerative braking without activating wheel cylinders servicing wheels which are being braked regeneratively. |
